12th Illinois Volunteer Infantry Regiment

The 12th Illinois Volunteer Infantry Regiment was a Union Army regiment which was active from 1 August 1861 to 18 July 1865 during the American Civil War. Raised by John McArthur, it was nicknamed the "1st Scotch Regiment", as most of its members were Scottish immigrants from Chicago, Illinois. It first fought at the Battle of Shiloh in 1862, and it later took part in the sweep through Georgia during the Atlanta Campaign and fought in the final Battle of Bentonville in 1865. It was mustered out on 18 July 1865.
